/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 57158.142312 0.000365 0.14926 0.01151 1.00000 0 22.63702 0.62872 21.04488 0.58450 3.37890 0.24305 3.14129 0.22596 57158.143032 0.000356 0.16272 0.01256 0.99187 0 21.87564 0.63428 20.03337 0.58074 3.55952 0.25456 3.25757 0.23298 57158.143759 0.000370 0.15827 0.01222 0.98438 0 21.45503 0.61166 19.94773 0.56869 3.39576 0.24363 3.15719 0.22651 57158.144505 0.000376 0.14585 0.01136 1.00000 0 22.26929 0.61723 20.70410 0.57385 3.24796 0.23632 3.01968 0.21971 57158.145252 0.000370 0.15182 0.01182 1.00000 0 21.86722 0.61681 20.30153 0.57262 3.31981 0.24093 3.08252 0.22369 57158.146021 0.000399 0.14074 0.01092 0.99275 0 21.99104 0.59364 20.38222 0.55022 3.09503 0.22517 2.86539 0.20849 57158.146860 0.000440 0.13198 0.01010 0.99342 0 21.36371 0.55781 19.86089 0.51857 2.81961 0.20282 2.62121 0.18855 57158.147673 0.000373 0.15581 0.01207 0.98450 0 21.53559 0.60795 20.02144 0.56520 3.35550 0.24212 3.11956 0.22509 57158.148385 0.000339 0.15696 0.01227 0.99145 0 23.19020 0.66322 21.56054 0.61662 3.63992 0.26484 3.38413 0.24623 57158.149100 0.000376 0.15351 0.01172 0.97692 0 22.14723 0.61325 20.59022 0.57014 3.39989 0.24193 3.16087 0.22492 57158.149794 0.000318 0.17630 0.01430 1.00000 0 21.34465 0.65354 19.84432 0.60760 3.76297 0.28266 3.49847 0.26279 57158.150500 0.000388 0.14119 0.01114 0.99254 0 22.20719 0.60430 20.64591 0.56181 3.13542 0.23211 2.91499 0.21579 57158.151227 0.000339 0.16495 0.01301 1.00000 0 21.78794 0.64015 20.25623 0.59514 3.59400 0.26301 3.34134 0.24452 57158.151918 0.000353 0.15694 0.01238 0.97541 0 22.51542 0.63852 20.82650 0.59062 3.53356 0.26011 3.27156 0.24079 57158.152656 0.000385 0.13876 0.01067 0.98496 0 23.44237 0.62364 21.79459 0.57980 3.25295 0.23472 3.02430 0.21822 57158.153472 0.000431 0.13304 0.01022 0.99329 0 21.64277 0.57068 20.12103 0.53055 2.87937 0.20776 2.67692 0.19315 57158.154372 0.000469 0.15847 0.01083 1.00000 0 20.99969 0.53532 19.52320 0.49769 3.32791 0.21101 3.09392 0.19617
